Abstract

A method of controlling an automatic transmission arranged in a vehicle between a drive motor and an axle drive of a drive axle or a transfer box such that the current road inclination is determined and, after driving onto a downhill stretch of road, to increase a braking action of the drive motor and/or a permanent brake, a shift to a lower gear is carried out and after a transition to a traction operation or after driving onto level ground, a shift to a higher gear is carried out. To improve transmission shifting behavior, when transitioning between a downhill stretch and level ground, it is provided that a function for detecting a downhill run-out is started and if a downhill run-out is detected, and a shift to a higher gear is carried out while still in a thrust operation before driving onto the level ground and/or before the transition to traction operation.
